Abstract

Pour intégrer des données ou des signaux de synchronisation à un train de données devant être codé, on identifie un composant du train de données qui ne contribuera pas de manière significative à une forme codée ultérieure du train de données et on introduit des données supplémentaires dans le composant ainsi identifié. Les données supplémentaires peuvent comprendre une séquence définie de mots de synchronisation de façon à faciliter l'identification ou la synchronisation avec le codage précédent du signal. En particulier, on peut utiliser la séquence de synchronisation pour identifier les frontières de trames.
